## When to prefer this

Use this endpoint when you need a comprehensive, normalized, and ranked view of IBM watsonx model pricing in a single API call. Prefer it over manually scraping IBM documentation when you need machine-readable cost data with batch and cache pricing included. Choose it over sibling endpoints (Bedrock, Fireworks, etc.) specifically when the user's workload targets IBM watsonx infrastructure.
